  • Several white-rot fungi collected from the mountains of Korea were evaluated for their ability to decolorize azo, polymeric, and reactive dyes. Strains CJ-105, CJ-212 and CJ-315, identified as Trametes sp., Pleurotus sp. and Fomes sp., respectively, showed higher potential for decolorization of those dyes in either solid or liquid media. For Trametes sp. CJ-105, 100ppm of Remazol Brilliant blue R and 500ppm of Acid Red 264 were completely decolorized after 2 days under liquid culture. The dominating ligninolytic enzyme existing in the culture broth was laccase (E.C. 1.10.3.2). Also, Pleurotus sp. CJ-212 and Fomes sp. CJ-315 showed similar patterns in decolorization of Remazol Brilliant Blue R and Acid Red 264. The extent of decolorization of the dyes in liquid culture was found to be proportional to the activities of the ligninolytic of decolorization of the dyes in liquid culture was found to be proportional to the activities of the ligninolytic enzymes produced by each strain. In addition to that Trametes sp. CJ-105 was highly effective in degradation of polycyclic aromatic hydrocarbons and pentachlorophenol by the activity of the ligninolytic enzymes produced. In this study, we found that white-rot fungi, Trametes sp. CJ-105(KFCC 10941), Pleurotus sp. CJ-212(KFCC 10943) and Fomes sp. CJ-315(KFCC 10942), were effective in decolorizing a wide range of structurally different synthetic dyes, as well as some chemical compounds which are known to be hardly degradable.

  • The concept for the decolorization in biological dye wastewater treatment systems is based on anaerobic treatment, for the reductive cleavage of the dyes' azo linkages, in combination with aerobic treatment, for the degradation of the products from azo dye cleavage, aromatic amines. Batch tests were conducted to examine the conditions and the factors affecting biological treatment of dye wastewater. From the tests, the removal efficiencies of organics and colors of dyeing wastewater were improved to $COD_{Cr}$ 27% and color 9% by injecting 10% of the domestic wastewater as a cosubstrate, and $COD_{Cr}$ 30%, color 22% with 30% injection of domestic wastewater. Therefore it was proved that decolorization efficiency is demonstrated with domestic wastewater as a cosubstrate. The analysis of aromatic amines in wastewater showed that decolorization was achieved by cometabolism while aromatic amines were produced by cleavage of azo bonds under anaerobic conditions and these products were removed in an aerobic tank subsequently.

  • 담자균류 백색부후균의 일종인 흰구름버섯(Coriolus hirsutus)을 실험균주로 하여 수종의 난분해성 방향족염료의 분해능을 측정하였다. 사용된 4종류의 염료 중, triphenyl methane 염료인 bromophenol blue가 탈색율 95% 이상으로 가장 잘 탈색되었으며, Congo red와 Poly R-478은 이보다는 낮은 57%, 55%가 탈색되었다. 그러나, heterocyclic 염료인 methylene blue는 본 균주에 의해 거의 탈색되지 않았으며, UV-visible spectrum상에서의 심색성 이동만 관찰되었다. 세포외 laccase와 peroxidase의 활성은 각 염료의 탈색율과 비례하여 나타났으며, 최대 활성 또한 최대 탈색시기에 관찰되었다. 효소의 활성 염색시 모든 염료의 탈색배지에서 공통적인 laccase와 peroxidase의 활성 띠가 관찰되었다. 이러한 결과로 볼 때, 세포외 laccase와 peroxidase가 난분해성 염료의 탈색에 중요한 역할을 할 것으로 판단된다.

  • Two new D-${\pi}$-A dyes were synthesized by the condensation reaction between active methyl and aromatic aldehyde and its biothiol sensing properties in DMSO/water were investigated by UV-vis spectroscopy. Upon addition of $Hg^{2+}$, the solution of D-${\pi}$-A dyes showed color change and the absorption band shows a formation of a dye-$Hg^{2+}$ coordination complex. These dyes exhibited high selectivity for $Hg^{2+}$ as compared with other cations. The dye-$Hg^{2+}$ could be recovered by adding glutathion(GSH). The absorption intensity of dye-$Hg^{2+}$ increased only by the addition of glutathione(GSH). The competition experiments revealed that no obvious interference was observed by performing the titration with the mixture of glutathione(GSH) and other amino acids. The results indicated that these D-${\pi}$-A dyes were highly selective for glutathione(GSH) detection.

  • A novel near infrared(NIR) absorbing dyes were synthesized by using bis-aldehyde formyl aromatic compounds and heteroaryl derivatives with the reactive methylene group. These dyes provided a range of the NIR wavelength region about 720 nm value. Also, the light absorbing properties of these dyes were investigated in our experiment results. In generally, these NIR colorants may be potential used for optical recording media, DNA sequencing probe and laser beam printings.

  • In recent years, there has been an intensive research on the application of degradative activities of fungi for treatment of various non-degradable materials such as petroleum hydrocarbons, polychlorinated biphenyls, pesticides, polycyclic aromatic hydrocarbons, dyes and so on. Chief of all, the fungal treatment technology is received the spotlight as one of the most promising alternatives to replace present methods for the treatment of dye wastewater. The present paper reviews the recent trend in research on the decolorization and biodegradation of dyes by various fungi, and improvements in bioreactors and bioprocesses involved the fungal treatment of dye wastewater. It also discusses alternatives and perspectives for the innovation of mycoremediation to treat dye wastewaters.

  • 본 연구에서는 백색부후균 중 줄버섯, 단색털구름버섯, 산느타리 및 유관버섯 등의 균사체를 이용하여 congo red, amaranth, orange G 및 methylene blue 등의 합성염료 탈색에 관한 실험을 수행하였다. 실험 결과 줄버섯과 단색털구름버섯은 congo red가 함유된 고체와 액체배지에서 이들 염료를 93~95% 탈색하였으며 amaranth는 약 80%, orange G는 62~70% 탈색시키는 것으로 나타났으나 유관버섯에 의한 3종류의 염료 탈색율은 30% 내외로 매우 낮았다. congo red, amaranth 및 orange G 등 각각의 염료가 첨가된 배지에서의 염료 탈색율은 이들 배지에서 배양한 균사체의 생장과 상관관계가 있는 것으로 나타났다. 그러나 모든 공시 균주는 methylene blue가 함유된 고체와 액체배지에서 methylene blue를 효과적으로 탈색하지 못하는 것으로 나타났다. 공시된 백색부후균의 액체 배지에서의 리그닌 분해효소 생산을 탐색하기 위해 1%의 나프탈렌이 첨가된 PDB 배지에 공시균을 10일 간 배양 후 효소의 종류와 양을 분석한 결과 모든 공시균은 laccase, lignin peroxidase 그리고 manganese peroxidase 등의 효소를 생산하는 것으로 확인되었으며 공시균주 중 줄버섯이 리그닌 분해 효소의 생산이 가장 왕성한 것으로 나타났다.

  • In order to improve dye uptime and wash fastness on dyeing of cotton fabrics with Amur cork tree, twitter ionic groups, acid groups, hydrophobic groups or cross linkage were introduced into cotton fabrics. Results obtained were as follows, 1 The optimum modification of cotton fabrics was carbosy methylation in the water solution containing 15% sodium chloroacetate and 15% sodium hydroxide and then introducing hydrophobic groups by treating in the solution containing $30m\ell$ DMSO and $3m\ell$ 2,4-TDI 2. Numbers of carbon, diisocyanate group than monoisocyanate group and aromatic compound than aliphatic compound in introduced hydrophobic groups were effective. 3. The dye uptake and wash fastness wore enhanced significantly by treating only with 2,4-TDI. 4. The wash fastness seems to correlate to the degree of swelling of the fabric during washing and also depend on the Interaction between dyes and acid groups as well as hydrophobic groups.

  • Research to dyeing properties of Ulmi cortex extract, silk and cotton fabrics were dyed and mordanted. Dyes were extracted from distilled water according to different pH values. The dyeability of Ulmi cortex extract were evaluated by conditions of dyeing temperature, dyeing time, dyeing pH, mordanting temperature, mordanting time, mordanting concentration and color fastness, etc. IR spectrum possessed absorption band of -OH at $3400cm^{-1},\;C-H\;at\; 2940cm^{ -1},\;aromatic\;C=C\;at\;1628cm^{-1},\;1518cm^{-1},\;C-O\;at\; 1107cm^{ -1},\;1043cm^{-1}$. And the $\labmda$max of extract appeared at 220nm and 280nm, so the substance of Ulmi cortex extract were catechin and tannin. Surface color of dyed fabrics were reddish yellow~yellow~greenish yellow. From the color fastness test, the fabrics dyed with PH 7 extract were excellent in irradiation and washing. Mordanting improved the color fastness and K/S value of dyed fabrics.
